I performed a full set of measurements on the SAE 2HP-D, using my Audio Precision SYS2722 system (see the January 2008 "As We See It"). Usually, before doing any testing of a power amplifier, I precondition it by running it at one-third power into 8 ohms for an hour. (With an amplifier having a class-B or -AB output stage, this power level results in the highest thermal stress on the output devices.) However, the 2HP-D is a very powerful amplifier, and I don't have a test load that could handle both channels running at 250W for an hour without overheating. So I…

A wise man once told me that people often forget that before they made studio masterpieces like the The Beatles aka The White Album or Abbey Road, the Beatles, until 1966 when they stopped touring, were one hell of a live act. If it wasn’t for all that screaming!
The problem for true believers is that there’s never been a proper Beatles live album. The closest we’ve come is 1977’s Live At The Hollywood Bowl which was a collection of 13 cherry-picked tracks, compiled by George Martin, from the band’s 1964 and 1965 appearances at the famed venue. Opinions on the album remain mixed. Fans who…
You read that correctly. 2017 will see the advent of two, potentially competing high-end audio shows, located just 35 miles and several congested freeways apart in Southern California. The first, the new Los Angeles Audio Show (LAAS), will take place June 2–4 in the Sheraton Gateway LAX, and is produced "in collaboration with the Los Angeles & Orange County Audio Society" (LAOCAS). The second, a continuation of T.H.E. Show Newport that was founded by the late Richard Beers and formerly supported by LAOCAS, will be held September 21–24 (September 21 reserved for press) in the Hilton…
Devialet Event in Cambridge MA Thursday, September 29, 6–8pm, Blink High End (129 Franklin Street, Cambridge, MA 02139) is holding a special event.

One of America's most vital living composers—New Yorker Steve Reich—turns 80 on October 3. In celebration, Deutsche Grammophon and ECM, two companies that greatly helped build Reich's reputation by recording his initially uncategorizable forays into minimalism, have reissued their seminal efforts. Given that all recordings feature members of the Steve Reich Ensemble (including the composer), and that Reich would not authorize performance and recordings of his work by others until 1990, the recordings are definitive (footnote 1).
From DG comes the 3-LP set, Steve Reich: Drumming, a reissue…
They don't make 'em like they used to.
That aphorism has few fans among people shopping for cancer drugs, contact lenses, GPS receivers, and laptop computers, all of which seem to get better with each passing year. Hell, even I know that.
It earns a more positive reply from anyone who's shopping for an oriental rug, or a fly rod, or a tweed jacket, or a musical instrument—people who will tell you that their fond response to the market for vintage examples of such goods is motivated by two things: older products were better made than their newer counterparts (better designs,…
The result is that, in certain aspects of their performance, many audio products made in the 1930s through the 1960s outperform virtually everything made since that time, often by generous margins. Those breathtaking levels of realism have yet to be matched, let alone exceeded.
I was about to add my usual, polite qualifier: It all depends on whether those performance parameters are important to you. But screw that. The fact is, contemporary audio consumers are even worse than contemporary audio designers when it comes to letting go of the things they think they know, in an effort to…
The second I encountered Dynaudio's Focus 200 XD powered loudspeaker at the High End 2015 show in Munich, Germany, it called to me. I wasn't so much drawn to its unique functions—which I describe below—as by the fact that it could help fill the black hole left by the dismantling of my reference system for my move from big, badass Oakland, California to the small, magical town of Port Townsend, Washington.
Until the completion of renovations to our future music room, my reference system would have to be my desktop system, built around a pair of Dynaudio Focus 110A powered loudspeakers,…
I listened to the Dynaudio rig both on my desktop and in the large classroom at nearby Peninsula College, where I taught classes in "Voices that Touch the Heart." Finally, I gave the setup a workout in my large, cathedral-ceilinged living room using Dynaudio's Stand 6 stands ($499/pair.) No matter where I played the Focus 200 XDs, they inspired a mixture of profound appreciation and disappointment. While the sound was clear, powerful, laudably neutral, and free of distortion, I consistently heard a bit of dryness at the centers of the voices of singers I've heard in person. That dryness lay…
